What does "shriveling" refer to in peanuts?

"Shriveling" refers to a defect in peanuts characterized by kernels appearing sunken and dry. This condition often arises due to the loss of moisture, which can occur during the drying process or through improper storage methods. The visual manifestation of this defect typically includes a lack of plumpness in the kernel, leading to an appearance that is shriveled or wrinkled.

When peanuts are exposed to environmental factors such as low humidity or excessive heat during storage, the moisture content can diminish, resulting in the dry, sunken characteristics seen in shriveled peanuts. This defect not only affects the aesthetic quality of the peanuts but can also influence their flavor and texture, making them less appealing to consumers. Understanding this defect is crucial for peanut inspectors to ensure the quality and safety of the product being evaluated.
